[Elecraft] Two-tone test for K2 SSB

[Don Wilhelm]

Ed,

You connect the 2 Tone generator output to the AF pin on the microphone 
jack and the generator ground to the ground pin on the microphone jack.
You can ground the PTT pin on the microphone jack to put the K2 into 
transmit.

Note that I did not specify the exact microphone jack pins - that is 
because the K2 can be configured to use a large number of microphone 
plug pinouts, and you did not specify which microphone you are using 
with the K2.  See the KSB2 instruction manual for detail on the 
microphone configuration header.  If you bought the K2 used and do not 
know how the microphone configuration jack is wired, you may have to 
remove the front panel assembly and compare the header wiring with the 
information in the KSB2 manual.

The rest of the instructions for setting the relative levels in the 2 
tone generator can be found in the 2TGEN manual.

On the antenna side of the K2, connect a dummy load to the antenna jack 
and connect your 'scope to the dummy load using a 10X probe to observe 
the resulting RF waveforms.

73,
Don W3FPR
